To avoid using the fresh water of the tank, it is possible to get connected with an external water system through the inlet (1).
By means of this connection, all uses on board are supplied, without using the fresh water pumps located in the engine room.
Once you have connected the system, check the pressure of incoming water by means of the pressure gauge located in the engine room and, if necessary, set the pressure by means of the relevant knob of the pressure relief valve.
The piping must be disconnected during the periods the yacht is unattended.
